They show how to enforce "observational purity". I don't remember people discussing this here. They use observational purity just for methods called by contracts, to find a trade-off between flexibility and analyzability. I don't remember this discussed in this newsgroup. So, it's not a so boring paper as you say. Bye, bearophile
